I really thought hard about posting this one (for the fear that my dear old wine would become trendy) but here goes.
One trick you should take to heart as a wine consumer is to NOT chase the hot wine of the day. An example would be buying Pinot Noir after Sideways was released. Wine prices spike according to popularity, so I like to buy lesser known wines for a better value and product.
One hugely underappreciated wine varietal is Aglianico from Southern Italy. Aglianico is sometimes referred to as the poor man's Barolo and is grown primary in Campania and Basilicata (Aglianico del Vulture).
Aglianico has huge flavor and high acidity (making it popular for roast lamb and other meats, as well as the summer tomato salad, olives, cheese, and bread type meals). The wine can also age, which is another plus. A nice bottle can be purchased for $13-$20, $40-$70 will probably get you the best tasting wine you've consumed over the last 10 years (especialy if you've been drinking Pinot, Cabernet, Shiraz, etc. which carry huge premiums for better bottles).
Update: Eric Asimov of The NY Times recently covered Aglianico on Sept 17th 2008, so the secret is now really out! He recommended the following bottles (I bought two cases of the Cantina di Venosa and it's a great value!):
